METALLIC STRUCTURE FOR THE TOPS OF RECEPTACLES.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed July 8, 1914. Serial No. 849,734.

To all whom it may concern Be it known that I, MILTON O. ADAMS, acitizen of the United States, residing at Kansas City, in the county ofJackson and State of Missouri, have invented certain new and usefulImprovements in Metallic Structures for the Tops of Receptacles; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to metallic structures, and particularly tometallic coverings or tops for receptacles, and aims to provide aone-piece structure adapted to serve as such a covering and also formedwith an upright marginal molding so constructed as to embrace and beretained by ?o the upper edges of the walls of thereceptacle.

It is also one of the objects of the invention to arrange one of themarginal molds where the structure is employed in connection withspecial forms of receptacles rethe invention will now be described withreference to one form of embodiment thereof which has been found to bethoroughly practical and eflicient, as illustrated in the accompanyingdrawings, after which those features deemed to be novel will beseverally specified in the appended claims.

In the drawings-Figure 1 is a perspective view of a receptacle providedwith a top or cover embodying the present improvements; Fig. 2 is afragmentary side elevation of the same; Fig. 3 is a central verticalsection through the receptacle and cover, extending from front to rear,the receptacle being partially broken away; Fig.

0 4 is a plan view of the blank from which the top or cover is molded;Fig. 5 is a bottom plan view of the top or cover after the same ismolded; and Fig. 6 is a fragmentary perspective View of the removablecap or lid used in connection with the cover opening.

Referring to the drawings, the top or extension, when desired.

cover member proper is constructed from a continuous sheet of metal 2,as illustrated in Fig. 4, which sheet is stamped by suitable cuttingmechanism for cutting out the blank indicated by the full lines in saidfigure. This results in a blank having the main or rim portion 4; thecentral opening 6, the corners of which are slit, as at 8; the marginalportions 10 with the scalloped ends 12; and the marginal extension 14provided with the rivet holes 16 and the bracket-forming portions 18 (incase it is desired to provide integral bracket portions in this manner).By suitable die action, the metal between the slits 8 is deflecteddownward at right angles to the rim portion,

along the dotted lines 20 in Fig. 4, thereby forming the flanges 22,while simultaneously the marginal portions 10 and the extension 14 aredeflected in the opposite direction along the dotted lines 24; and inthe same operation lines of corrugations 26 are formed parallel to themarginal portions 10 between the same and the opening 6. By means ofsuitable tools, the marginal portions are then rolled outward, downwardand inward to form upwardly projecting beads around the front and sidesof the cover, as illustrated inFigs. l to 3, the rear ends of the sidebeads being slightly flattened, as shown at 28, and the ends at thefront corner edges 12 fitting exactly to gether and forming, whensoldered-or otherwise secured, a miter joint at each of said corners. Inthe case of the extension 14, the same is folded along the severaldotted lines 30 to form an upright wall across the rear of the cover,having flat front and rear clamping faces to permit the mountingofsuitable attachments upon the The extension 14 is hollow or tubular, anddesigned to be fitted with a wooden filler 32see Fig. 3. The rear edgeof the metal comprising the extension 14 is downturned to extendparallel with thefront wall of the extension and slightly spacedtherefrom; and similarly, the outer margins of the metal forming thebeads 10 are slightly spaced from the inner walls of said beads, so thatthere is thus provided a downwardly opening channel 34 entirely aroundthe rim portion 4 for the purpose of fitting the cover upon the upperedges of the walls 36 of the receptacle to which the coveris to beapplied. When mounted in this manner, the cover may be secured bysoldering the same to the receptacle walls, or by means of rivets 38, asillustrated in the case of the extension 14, passing through theopenings 16.

Suitable angle brackets l0 may be provided for bracing the extension 14from the upper face of the rim at, but it is preferred to employ theintegral bracket-forming portions 18 already referred to, which arefolded forward and their free ends bent inward and secured to the rimportion l by additional rivets 38. These portions 18 thus serve not onlyas brackets but also as a means for closing up the ends of the tubularextension 14 and preserving the neat out- Ward appearance of the latter.Prior to fitting the top or cover upon the receptacle, a reinforcingband 42 is fitted around the flanges 22, and, by means of a suitable diemechanism, the flanges are deflected and clamped about said band, andthen secured thereto by rivets 4:4: passing through the ends of theband.

For closing the opening 6, a removable cap or lid 46 is provided, whichis also made from a single piece of sheet metal, being of angularcontour corresponding to that of the opening, and doubled back uponitself at its borders to form shoulders 48 adapted to rest upon theedges of said opening (see Fig. From the inner margins of the doubledportions or shoulders are provided downwardly projecting flanges 50 forfitting within the opening 6, the bottom edges of which flanges arefolded back upon themselves. At each corner, moreover, one of theflanges 50 projects sufliciently to overlap the end of the adjacentflange, and the lower edge of the latter is folded over this overlappingend, as clearly shown in Fig. 6, thereby affording a firmly braced andsubstantial construction; it being noted that the end portion of saidprojecting flange is reduced somewhat in width to permit the foldingover of the adjacent flange.

From the foregoing it will be apparent that an extremely simple andefiicient construction has been devised for fulfilling the objects ofthe invention. The mode of formation which makes use of the angular,rolled and folded construction, renders the device most rigid anddurable, and, each of the parts being of one piece of sheet metal andthe process of constructing the same being of but few steps oroperations, the cost of producing the structure is quite low. Moreover,the integral construction has another important advantage in that thenumber of joints and crevices or seams is reduced to a minimum, which isa very desirable feature, especially where it is sought to provide assanitary structures as possible. This is particularly true in the caseof washing apparatus, for which the structure described is quitefavorably adapted, the rolls or beads 10 and the extension 14 forming aretaining wall about the top to guard against the waste or dripping ofwater out over the sides of the receptacle, and the extension let alsoserving as a firm and substantial support for the attachment of thewringer commonly applied to the washing machine; but while the useillustrated has been with particular reference to this adaptation of theimprovements, the invention is also well adapted to other types ofreceptacles, such as to the covers of fire-proof grain bins, waste ortrash receptacles, well copes, etc.

The foregoing represents what is now conceived to be the preferred modeof practising the invention, but the right is reserved to such changesor modifications as may fairly fall within the scope of the appendedclaims.
